APPARATUS FOR MOVING SWITCH-RAILS.

SPECIFICATION forming part of Letters Patent No. 791,026, dated May 30,1905.

Application filed February 1'7, 1905. Serial No. 246,047.

To all whom it pea/y concern.-

Be it known that I, MARQUIS D. I-IANLON', a citizen of the UnitedStates, residing at Wilkinsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inApparatus for Moving Switch-Rails, of which the following is aspecification.

My invention relates to apparatus for operating double-point movablefrogs, and particularly to that class of apparatus which comprises anelectric motor. 1 will describe adouble-point-movable-frog-operatingapparatus embodying my invention andthen point out the novel features thereof in claims.

In the accompanying drawings, Figure 1 is a top plan view of adouble-point movable frog and operating apparatus embodying myinvention. Fig. 2 is a View partly in elevation and partly in verticallongitudinal section.

Similar characters of reference designate corresponding parts in bothfigures.

A A indicate one pair of points, and A A the other pair. These pairs ofpoints are oppositely facing and adapted to cooperate with the bentrails A A to form two intersecting tracks, only one of which can becontinuous at the crossing at one time. Adjacent to these points is anoperating apparatus by means of which their positions are changed inorder to close one track and open the other, as desired. This apparatus,as shown in the drawings, comprises an electric motor B, a clutchmechanism O, a speed-reducing arrangement I), and two cam-cylinders Eand F, by means of which the locking and unlocking of the points, themovementof the points, and the movement of the usual detector bar orbars are secured. No detector-bar is shown, it being deemednotnecessary, as it is well known in the art. The detector bar or barswhich are used in connection with the points are preferably and as shownoperated from the cam- These several parts are mounted on a base-plateA, suitably secfired to the ties A The parts B, O, D, and E are ofsubstantially the same construction and operate in the same way as thesimilar parts described in my prior application upon which Patent N 0.762,997, dated June 21, 1904, was granted, and no detailed descriptionthereof is deemed necessary herein. The cam-cylinder E is provided withtwo cam-grooves 6 and a, which respectively operate the levers e and aThe lever e is connected by a rod 6' to the bridle-rod 0 joined to thepoints A A. The lever a is connected by a rod 0 with the locking meansand by a rod 6 with a detector-bar. (Not shown.) Other detector-barsadjacent the switch-points may be connected'with the lever 0 oradditional levers and connections may be provided for otherdetector-bars. The locking means is indicated by g and may be similar tothat illustrated in the said patent or of any other preferredconstruction, and g is a lockingbar connected to both points A.

So far as described the operating apparatus will move and lock thepoints A A and operate the detector-bar in a manner similar to that ofthe apparatus described in the said patent with respect to theswitch-rail A therein referred to.

In the present invention it is, however, desirable to move the points AA simultaneously with the points A A and in an opposite direction, andit is of course also necessary to lock the points A A. To accomplishthese two results, I prefer to use the same locking meansg to lock bothpairs of points and to employ another cam-cylinder F, having onecamgroove f only, similar to the cam-groove on the cylinder E.

f indicates a bell-crank lever similar to the lever 0 but oppositelydisposed, which is operated by the cam-groove f, and this lever isconnected by a rod f to the bridle-rod f joined to the points A A.

f* indicates a locking-rod suitably secured to both points A A andadapted to cooperate with the locking means g.

It is preferable to rotate the cylinder F simultaneously with thecylinder E and by means of the same motor, although this is not absolutely essential, as a separate motor might be employed to operate thecylinder F independently. As shown, however, the shafte of the cylinderE is extended beyond the standard 6 and the shaft f of the cylinder F isextended beyond its supporting-standard f, and a coupling f is connectedto the opposing ends of the shafts e and f by universaljoints f 8 and fItis obviousa single integral shaft might be used for both cylinders orthat only one universal joint might be employed between the two shafts;but the construction illustrated is deemed desirable, as couplings ofdifferent lengths may be utilized to suit different conditions, for thecylinders E and F may not always be placed the same distance apart.

It will be obvious from the foregoing description, taken in connectionwith the drawings, that when the motorB is operated both cylinders willrotate simultaneously and that both pairs of points will be movedsimultaneously, but in opposite directions, and that the locking meansfor both pairs of points will be operated by the cylinder E.

What I claim as my invention is 1. In an apparatus for moving two pairsof points, the combination of two cam-cylinders for moving therespective pairs of points, locking means common to both pairs of pointsoperated by one of said cylinders only, and means for rotating thecylinders.

2. In an apparatus for moving two pairs of points, the combination oftwo cam-cylinders for moving the respective pairs of points, lockingmeans common to both pairs of points operated by one of said cylindersonly, and an electric motor for rotating the cylinders.

3. In an apparatus for moving two pairs of points, the combination oftwo cam-cylinders for moving the respective pairs of points, lockingmeans common to both pairs of points operated by one of said cylindersonly, an electric motor for rotating the cylinders, and speed-reducingmechanism between the motor and the cylinders.

4. In an apparatus for moving two pairs of points, the combination oftwo cam-cylinders for moving the respective pairs of points, lockingmeans common to both pairs of points operated by one of said cylindersonly, an electric motor for rotating said cylinders, a speedreducinggear between the motor and cylinders, and an electric clutch between themotor and speed-reducing gear.

5. In an apparatus for moving two pairs of points, the combination oflocking means common to both pairs of points, two cam-cylinders, onehaving a cam-groove for operating one pair of points, and the other twocamgrooves one for operating said locking means and the other foroperating the other pair of points, and an electric motor for rotatingthe cylinders.

6.- In an apparatus for moving two pairs of points, the combination oflocking means common to both pairs of points, a detector-bar connection,two cam-cylinders, one having a cam-groove for operating one pair ofpoints, and the other having two cam-grooves, one for operating thelocking means and the detector-bar connection and the other, foroperating the other pair of points, and an electric motor for rotatingthe cylinders.

7. Inan apparatus for moving two pairs of points, the combination of twocam-cylinders for moving the respective pairs of points, a shaft havinga universal joint for connecting the two cylinders, and an electricmotor for rotating both cylinders simultaneously.

8. In an apparatus for moving two pairs of points, the combination oftwo cam-cylinders for moving the respective pairs of points, a couplinghaving a universal-joint connection with the shafts of both cylinders,and an electric motor for rotating both cylinders together.

9. In an apparatus for moving two pairs of points, the combination oftwo cam-cylinders and connections for moving the pairs of points inopposite directions, a locking means common to both pairs of pointsoperated by one of the cylinders only, and an electric motor forrotating the cylinders.

10. In an apparatus for moving two pairs of points and the necessarydetector bar or bars, the combination of two cam-cylinders, one formoving one pair of points and the other for moving the other 'pair ofpoints and the detector bar or bars, and means for rotating bothcam-cylinders and located nearest the cam-cylinder for moving thedetector bar or bars.

11. In an apparatus for moving two pairs of points and the necessarydetector bar or bars, the combination of two cam-cylinders, one formoving one of the pairs of points and the other for moving the otherpair of points and the detector bar or bars, and means for rotating bothcam-cylinders.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
